Abstract: A method is disclosed for making a plug-in fuse assembly like that disclosed and claimed in U.S. Pat. No. 3,909,767, granted Sept. 30, 1975 for Miniature Plug-In Fuse.

Abstract: In a process or method according to the invention the parts of an electrical contact device, such as a slip ring comprising the ring to receive the liquid metal and the probe or brush for contacting the liquid metal are treated by sputter etching to remove the parent metal oxide. Prior to exposure of the electrodes to any oxygen, a sacrificial metal is sputter deposited on the parts. Preferably this sacrificial metal is one that oxidizes slowly and is readily dissolved by the liquid metal. The sacrificial metal may then be removed from unwanted areas. The remainder of the ring and the probe to be wet by the liquid metal are submerged in the liquid metal or the liquid metal is flushed over these areas, preferably while they are being slightly abraded, until all the sacrificial material on these portions is wet by the liquid metal. In doing so the liquid metal dissolves the sacrificial metal and permanently wets the parent metal.

Abstract: The magnetic chuck disclosed herein is of the interlocking finger type and substantial components thereof are fabricated by making parallel oblique cuts in conventional bar stock thereby to generate a succession of parallelogram-shaped pieces. A series of the parallelogram pieces are assembled with alternate pieces being reversed so that they overlap only over a common triangular area with adjacent parallelogram pieces being separated by interleaved triangular spacers. The projecting fingers provided by such an assembly may be then mated with other similar or half-similar pole-piece units to form an interlock magnetic chuck top plate.
